It is desired to estimate the average time it takes statistics students to finish a computer project to within two hours at 90% reliability. it is estimated that the standard deviation of the times is 14 hours. how large a sample should be taken to get the desired interval? a) n = 189 b) n = 133 c) n = 325 d) n = 231

f(x)=2/3x-8, which give g(x) the greatest value.

step-by-step explanation:

55 degrees because 55+55=110 degrees

you are playing an adventure game on your computer. you come across a troll who won't let you pass and there is no other way to get to the other side of the river except over the bridge he is guarding.

the troll is a nerd. he takes great delight in watching people struggle with his problems. very few get them. he only gives you one chance and then he changes the puzzle. you have to solve this one.

before you are four blocks. they are numbered 11,6, -7,21.

he tells that the answer he wants is minus and between -1 and - 2. you can use +, -, ×, ÷   ( and ) as many times as you like or no times at all. you don't like the way he's looking at you, but you need to cross the bridge. what do you do?
